BACKGROUND OF THE INVENTION

[0004] The present invention relates to processing information content, and more particularly, to combining and/or separating segments of this content to simplify and otherwise facilitate translation and other processing functions associated with the content. Over the past few decades, opportunities for international relationships have expanded at a staggering rate. Many factors have contributed to this expansion—improved transportation capabilities, advances in communication and media technologies, opening of once inaccessible cultures, among others. More recently, the Internet (the World Wide Web, in particular) has provided seemingly unlimited access to international audiences. The Internet represents a massive global business opportunity, and has provided the means for a wide range of businesses to deploy a multilingual and multicultural marketing presence, thereby increasing revenue, improving customer loyalty and reinforcing brand recognition.

[0005] As information becomes available globally, the role of translators has shifted away from simple transcription of text into a target language. Translators always had to pay close attention to any attributes and linguistic idiosyncrasies of the target culture, as well as understand and adapt to these differences. Now, however, translators must also ensure the timely deployment of the translated content to the designated site. Translation can be made more efficient with greater flexibility in software functionality and the ability to save previous translations for future use. Traditionally, translators worked with hard copy documents, from which they had the flexibility to translate content at any suitable level. Thus, translators had the ability to look at an entire document and translate it without confines. The increased need for efficient content translation has motivated numerous companies to develop tools that automate at least part of the translation process.

[0006] To increase the overall speed of content translation, tools have been developed to save translations in some type of memory (referred to herein as “translation memory” or “TM”), so that the tool can make automatic substitutions, and the translator will not have to consider further instances of those translations. The TM provides a record of pairs of units of translation that have already been translated. A “unit of translation” is a segment of content that has been delineated by any of several criteria, as is discussed in more detail herein. Each associated pair in the TM includes a unit of translation from the content in the source language (i.e., the language of the content that is to be translated), and the corresponding translation unit from content in the target language (i.e., the language into which the source content is being translated). In order to populate the TM, prior art translation methods segment content into sentences (or other syntactic units, e.g., words, phrases, etc.) based on predetermined criteria so that the translator can focus on translating one sentence (or other syntactic unit) at a time.

[0007] However, differences between the source language and the target language create difficulties in translating directly from one language to another within the constraints of the particular segments chosen. Such differences may include, but are not limited to, differences in grammatical structure, differences in idiomatic expressions, and punctuation differences. Further, segments that are spatially adjacent in the source document may not necessarily be best suited as adjacent in the target content. Content generally cannot be translated word for word, sentence for sentence, paragraph for paragraph, because of these language differences. Another consideration is that competent, efficient translation is typically not deterministic. For example, three translators operating on the same content may well produce three different translations, each of which would be technically correct. Any type of segmentation tool that segments the content based on a rigid set of criteria will force a translator to approach translation of the content on a word for word (etc.) basis.

[0008] Flexibility in content segmentation is important because translators must be able to account for the differences in language structures. For instance, translating content sentence by sentence may populate a translation memory with more specific entries. Storing more specific entries in translation memory is useful because doing so increases the likelihood that future translation instances will make use of those entries. However, as described herein, a sentence-to-sentence translation may not be accurate, depending on the languages being used in the translation. For example, the following sentences in Italian:

[0009] Per quanto riguarda la Banca Centrale Europea, un euro debole può essere un problema soltanto se aumenta l'inflazione. Però, a 2.3%, l'inflazione nella zona euro è ancora abbastanza modesta.

[0010] would be translated as a single sentence in English:

[0011] Yet as far as the ECB is concerned, a weak euro is only really a problem if it pushes up inflation; and at 2.3%, inflation in the euro zone is still rather modest. (The Economist, Sep. 23-29, 2000, p. 89)

[0012] On the other hand, although translating an entire paragraph as a unit may be more accurate, it can be inefficient for translators because doing so will populate the translation memory with entries that are unlikely to be used again.

[0013] An additional problem with content segmentation is determining the sentence boundaries. Typically, a period denotes a sentence end. Yet, if a word within a sentence is abbreviated and uses a period (e.g., “Mr.” ), the period following the abbreviation could be interpreted as a sentence end and the sentence would thus be segmented at that point. Likewise, some languages such as Thai do not even use period punctuation.

[0014] It is an object of the present invention to substantially overcome the above-identified disadvantages and drawbacks of the prior art.

SUMMARY OF THE INVENTION

[0015] The present invention provides a method of and system for splitting and merging blocks of information content (e.g., textual blocks) so as to simplify and expedite a translator's task in converting content from one language to another. The method and system of the present invention is referred to herein, in general, as “Split/Merge.” The textual information to be translated from one language to another is referred to herein as “content.” The Split/Merge method and system allows a user (i.e., a translator) to decide, in real time, the level at which he or she wishes to translate content. The translator has the ability to “split” a paragraph into separate sentences, allowing for individual translation of each sentence. Thus, the translation memory contains entries at the sentence level, which are more likely to be repeated than entire paragraphs. In addition, the translator can “merge” selected sentences together to form a single segment for translation. Furthermore, the translator can “merge” all sentences of a paragraph into a single textual “chunk,” as well as merge all of the paragraphs into a larger textual “chunk”. This split/merge functionality provides flexibility for source material that is not suitable for sentence-by-sentence translation.

[0016] The utility of the Split/Merge invention may be exploited in a translation system such as Idiom's WorldServer. In general, WorldServer is a Web-based application that enables enterprises to manage their content while leveraging established Web architecture, content management and workflow systems. A translator uses WorldServer to determine what content he or she needs to translate. The translator can either export the content needing translation to a third party editing tool, or use the Translation Workbench to perform the actual translation. A translator can be an individual contributor, including users that are adapting but not translating content and reviewers who review content.

[0017] The Split/Merge feature of the present invention provides value for translators by giving them greater flexibility of how to translate content before performing the translation. In addition, increased flexibility in segmentation will populate the TM with more utilizable entries.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0080] One embodiment of a method 100 for splitting and merging blocks of information content according to the present invention is shown in flow-diagram form in FIG. 1. In one aspect, the method identifies units of translation in a block of source content (hereinafter referred to as “source units of translation”) based on one or more delineating characteristics associated with the source content. Within the block of source content, individual source units of translation exist bounded by delineating instances. Examples of delineating instances include (but are not limited by) syntactic characteristics (i.e., the relationships among characters or groups of characters within the content), lexical characteristics (e.g., punctuation, character case, white space between characters), conceptual characteristics (e.g., semantics, such as characters or character groups that should be spatially adjacent to be proper in a particular language), multimedia content characteristics (e.g., proper relationships among various multi-media components), sound based characteristics (e.g., voice inflection), markup/formatting characteristics (e.g., an HTML document, or the row/column boundaries of a table), and markers manually inserted into the content by the translator.

[0081] In general, a translator (i.e., a person with knowledge of the target language and the source language; also referred to herein as a “user”) translates the source content by translating the individual source units of translation into target units of translation. A competent translator may desire to have the source units of translation formed by different delineating instances, as described above, depending upon the nature of the document. For example, in one area of content, a translator may wish to have the units of translation formed by lexical instances such as punctuation. Thus, in that area of content the units of translation could simply be phrases delineated by periods, commas, semicolons, etc. In another area of content, the translator may desire to have the units of translation formed by syntactical instances, such as grammatical structural boundaries. In yet another situation, a translator may be translating an Internet web page, so that the translator may want to use HTML markup characters as the boundary delineators for the units of translation. In other cases, the translator may desire to have a mixture of boundary delineators for the units of translation (e.g., HTML character on one boundary, and a lexical instance on the other boundary).

[0082] As FIG. 1 shows, the method 100 begins by selecting 102 at least one, but possibly several, delineating characteristics in addition to lexical characteristics. The delineating characteristics are chosen in addition to lexical characteristics because the use of lexical characteristics alone is nearly trivial. In other words, segmenting the content by sentences delineated by periods, or phrases delineated by commas, is a relatively common practice. However, segmenting the content using other criteria, either alone, in combination with lexical characteristics, or combinations thereof is novel and an important aspect of the present invention. The method 100 then determines 104 of instances of the selected delineating characteristics within the source content, and identifying at least one pair of the instances in the content. The pairs of instances do not need to be consecutive within the content, although in many cases they will be consecutive. The method 100 then evaluates individual pairs of instances of delineating characteristics. The method 100 associates 106 the first instance of a pair with a first boundary of a source unit of translation, and associates the second instance of the pair with a second boundary of the source unit of translation. Thus, the method 100 identifies the source units of translation within the content by using the various delineating characteristics. In general, the pairs of instances will both be the same type of characteristic, i.e., both lexical, or both syntactical, etc. In other embodiments, the method may identify units of translation via a hybrid pair of instances, i.e., the first instance may be syntactic, and the second instance could be conceptual, as described herein. In some embodiments of the invention, the translator (i.e., the user) selects the delineating characteristics (step 102) and the remaining steps (steps 104 and 106) are completely automatic. In other embodiments, the translator provides input to steps 104 and 106 as well. For example, in some embodiments the actual instances within the content may be automatically determined, and the translator may manually select (via keystrokes or mouse clicks on the computer, for example) which instances should be paired.

[0083]FIGS. 2A, 2B and 2C illustrate a sample source paragraph segmented into source units of translation by the method 100. FIG. 2A illustrates the sample paragraph 110 and the list 112 of selected delineating characteristics. For simplicity in this example, only “lexical” characteristics are included, although other characteristics, alone or in combination, may also be included in the list. FIG. 2B shows the delineating instances 114 determined within the content, and the pairs 116 the method 100 identifies. FIG. 2C shows the first boundary 118 and the second boundary 120 of each unit of translation 122 as determined by the method 100.

[0084] In one embodiment of the invention, the method 100 further identifies 108 one or more target units of translation, and assigns 109 associations between source units of translation from the source content to target units of translation within the target content. In general, the associations among the target units and the source units of translation are dictated by the language translation the translator performs from the source content to the target content. The association may be, but is not necessarily, a one to one relationship between the source unit of translation and the target unit of translation. In some cases, two or more source units of translation may be associated with a single target unit of translation. In other cases, a single source unit of translation may be associated with two or more target units of translation. In general, the translator defines the initial association during the act of translation. The source-to-target associations are typically stored in translation memory (TM), so that future occurrences of the source unit of translation in the source content can be automatically associated to a target unit of translation.

[0085] The source units of translation are typically characterized by an adjacency pattern, i.e., the first source unit of translation is adjacent to the second source unit of translation, the second source unit of translation is adjacent to the third source unit of translation, etc. In some embodiments, the method enforces this adjacency pattern during the association with the target units of translation, so that the target content follows the adjacency pattern of the source content. In other embodiments, the nature of the language dictates that the target units of translation do not follow the adjacency pattern of the source units of translation. One example of this is when the source content is interspersed with comments or other non-essential content segments. In this case, the translator may wish to delete the comments from the target content, and would simply not associated the source units of translation that contain the comments with any target units of translation.

[0086] In one embodiment of the invention, the method merges the target units of translation into a hierarchical structure. FIGS. 3A, 3B and 3C illustrate an example of hierarchical structuring. FIG. 3A shows source content as paragraphs (and the sentences that form the paragraphs) represented as separate, contained segments or bigger paragraphs that contain sub-paragraphs. FIG. 3A also shows the content broken down into the first level of hierarchy—the three main paragraphs in the content. FIG. 3B shows the hierarchical breakdown of the first paragraph, and FIG. 3C shows the hierarchical breakdown of the third paragraph. Note that the second paragraph is a single sentence, and so no further hierarchical breakdown is necessary. In the most extreme case, the entire content could be represented as one segment. With the present invention, the user (i.e., the translator) has the ability to configure how paragraphs can be merged. For example, if the server upon which the Split/Merge is resident is configured such that paragraphs with blank lines between them can be merged, the user may segment the Example shown in FIG. 1 as depicted in FIG. 2. A box represents one segment that can be translated separately (assuming that it is not a Tag only segment). The user can merge segments that are siblings (sentences within a paragraph) and translate the result as one segment. Likewise, the user can split a segment that contains children and translate each child separately. While the user can dynamically split and merge the segments, they can only view one level for any given node at a time. For example, the user can not translate at the paragraph and sentence level for the same paragraph at the same time. They can, however, decide to translate one segment as a paragraph, and a different paragraph at the sentence level. In one embodiment, the translator may provide one or more hierarchy criteria, such that the method merges the target units of translation into a hierarchical structure defined by the criteria. In other embodiments, a fixed, predetermined set of hierarchy criteria may be accessible by the method for hierarchical structuring of the target units of translation.

[0087] Another aspect of the invention includes a method 150 of selecting the one or more segmentation criteria that are used to identify source units of translation in a block of source content. The segmentation criteria identify the delineation characteristics described herein that define the boundaries of the source units of translation. The method 150 includes providing 152 a set of two or more source segmentation criteria that are associated with the block of source content. The method 150 also includes selecting 154 one of the source segmentation criteria as an “initial” source criterion that is used for defining boundaries of the first source units of translation within the source content. The method 150 further includes dynamically selecting 156 subsequent source segmentation criteria from the set of source segmentation criteria as the boundaries of the source units of translation are defined. The dynamic selection is done as a function of one or more external factors, typically including inputs from the translator as he or she performs the translation. Thus, in one embodiment of the method 150, the translator designates several segmentation criteria that identify delineation characteristics that may be useful in segmenting a particular block of source content. In some cases, the segmentation criteria may simply be the delineation criteria themselves, as defined herein for the method 100. In other cases, the segmentation criteria may include higher-level translation goals that imply the use of a particular set of delineation characteristics. In other cases, the segmentation criteria may be real time input from the translator (such as keystrokes, “point and click” via a mouse interface, or voice inflections). Once a set of segmentation criteria have been designated, the translator selects one (or possibly more) of the criteria to be used initially. As the translation proceeds, the translator may change the criteria “on the fly,” i.e., dynamically selecting criteria from the designated list as the translator deems appropriate for the content.

[0088] In one embodiment of the invention, the method 150 further includes selecting 158 one or more segmentation criteria that are used to identify target units of translation for a block of target content. Similar to the source segmentation criteria, the target segmentation criteria identify the delineation characteristics that define the boundaries of the target units of translation. In some embodiments, the set of target criteria and source criteria may be identical, i.e., a common set of criteria may be used for both target and source criteria. The method 150 further includes providing 160 a set of two or more target segmentation criteria that are associated with the block of target content. The method 150 also includes selecting 162 one of the target segmentation criteria as an “initial” target criterion that is used for defining boundaries of the first target units of translation within the target content. The method 150 further includes dynamically selecting 164 subsequent target segmentation criteria from the set of target segmentation criteria as the boundaries of the target units of translation are defined. As with the source content, the dynamic selection is done as a function of one or more external factors, typically including inputs from the translator as he or she performs the translation. The external factors may also include, among other things, information related to the content itself, such as HTML code that describes the layout of a web page, or data file that provides the structural layout of the source document. The method 150 also assigns associations among the source units of translation and the target units of translation. In general, the associations among the target units and the source units of translation are dictated by the language translation the translator performs from the source content to the target content. The association may be, but is not necessarily, a one to one relationship between the source unit of translation and the target unit of translation. In some cases, two or more source units of translation may be associated with a single target unit of translation. In other cases, a single source unit of translation may be associated with two or more target units of translation. In general, the translator defines the initial association during the act of translation. The source-to-target associations are typically stored in translation memory (TM), so that future occurrences of the source unit of translation in the source content can be automatically associated to a target unit of translation.

[0089] A computer-based system 200 for splitting and merging blocks of information content according to the present invention is conceptually illustrated in FIG. 4. In one embodiment, the system 200 includes a user interface 202, a content processor 204, a segment processor 206, and a translation memory (TM) 208, all resident on a computer system 210 such as a personal computer, workstation or similar system known in the art. The user interface 202 provides a mechanism for a translator to select the delineating characteristics in addition to lexical characteristics, as described herein. In one embodiment, the translator selects from a group of predetermined characteristics. In other embodiments, the translator is provided the option of entering his or her own characteristics that may be unique to the source and/or target content. The user interface 202 also provides the translator a mechanism for manually inserting delineating markers so that the translator can manually segment units of translation. The user interface may include a keyboard input for keystrokes, a mouse input for point-and-click input, or a voice recognition processor for recognizing voice commands and inflections. The user interface also provides an output interface to the user from the system 200, so that the translation procedure is interactive.

[0090] The content processor 204 then analyzes the source content and determines instances of the selected delineating characteristics within the source content. The content processor also identifies one or more pairs of instances from all of the instances it finds. The pairs of instances do not need to be consecutive within the content, although in many cases they will be consecutive. The segment processor 206 then evaluates individual pairs of instances of delineating characteristics. The segment processor 206 associates the first instance of a pair with a first boundary of a source unit of translation, and associates the second instance of the pair with a second boundary of the source unit of translation. Thus, the segment processor 206 identifies the source units of translation within the content by using the various delineating characteristics, as described herein. In one embodiment of the invention, the segment processor 206 further identifies one or more target units of translation, and assigns associations between source units of translation from the source content to target units of translation within the target content, as described herein. In general, the translator defines the initial association during the act of translation. The source-to-target associations are stored in TM 208, so that future occurrences of the source unit of translation in the source content can be automatically associated to a target unit of translation.

[0091] The system 200 also allows the translator to dynamically select and vary the segmentation criteria the system uses to identify source and target units of translation, and to dynamically vary the criteria the system uses to merge the target units of translation after they have been formed. The translator provides a set of source and target segmentation criteria to the system via the user interface 202. The translator selects, also via the user interface 202, initial source and target segmentation criteria, and the user interface 202 provides these selections to the content processor 204 and the segment processor 206, which in turn utilize the selections to segment and merge the units of translation. As the translator performs the translation of the source content into the target content, he or she may decide at some point in the translation that the current segmentation criteria is not suitable, and that different criteria would be more appropriate. The translator may, “on the fly,” provide new segmentation criteria to the system 200 via the user interface 202, selected from the set of criteria entered earlier. The segment processor 206 subsequently uses the new segmentation criteria to segment and merge content thereafter.

[0092] The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of the equivalency of the claims are thus intended to be embraced therein.
